Actually, this line is supposed to appear before all other lines
because it's a top level expression. Top level expressions aren't part
of the function's output, so they must appear first. Adding a newline
before it is tantamount to adding a binary expression to the output,
which means that the top level expression doesn't precede all output
expressions anymore. I could change the error to a warning, but first,
can you show me a template that absolutely requires changing the
existing error handling behavior?
